Is there a perfect code of grammar?

The correct choice reflects the understanding that grammar is indeed subject to change over time and is influenced by a variety of factors, including cultural shifts, technological advancements, and communication trends. Language is a living entity that evolves, adapting to the needs and practices of its speakers.

What may be considered grammatically correct in one era or region can shift as slang becomes more accepted, new forms of expressions are introduced, or as societal norms evolve. This emphasizes that there is no universal, unchanging set of grammatical rules that applies perfectly in all contexts. Instead, grammar is dynamic and varies across different dialects, languages, and even communities, indicating that ongoing dialogue about grammar is essential.

A misunderstanding here might suggest that there's a fixed set of rules that everyone adheres to, which far from captures the reality of how language operates. The perception of a 'perfect code' often overlooks the fluid nature of communication and the personal and contextual factors that influence language use. Thus, affirming that grammar is subject to change provides a more accurate view of the relationship between language and society.
